How to calculate salary inflation

[AGD]

Hi,

Are there any good sites where you can put in your salary and when it started and see what it should be now taking into account inflation (either CPI or RPI)?

I just assumed there would be a site for this but I can't seem to find one.

Or failing that, just a site where you can enter a time period (from a month to another month) and it will tell you the inflation in that time period?

Thanks!

The time period I want just happens to fall into a half year and all the figures you find are annual only. All the calculator sites I've found only go up to 2011 and don't do it month to month.

I can't do accurate 'elementary math' without the monthly data! I can make estimates from the annual data for each months though which is what I've done so far. It just seems amazing that there isn't a website for this already!

Semi-pro: thanks but unless I'm missing something, the GDP deflators don't give me any different info to the annual inflation figures?

doesnt work for more than one year. In fact, just doesn't work.

Thanks, I'll bear that in mind.
